Abstract: A vessel for containing a sterilizing agent for use in a sterilization method wherein instruments to be sterilized and the liquid sterilizing agent contained in the vessel are located in the chamber of sterilizing apparatus which is closed and heated to evaporate the sterilizing agent and sterilize the instruments. The vessel comprises a central shallow first vessel part defining a central sterilizing agent-containing space which is surrounded by an outer second vessel part defining a supplemental space into which the sterilizing agent will flow should it overflow over the short brim wall of the central sterilizing agent-containing space.

Abstract: The invention is concerned with a method of storing and transporting a solution of peracetic acid or a solution with similar properties. In the system the solution of peracetic acid or the like is poured in one or more containers (1) in the plug (4) of which there is made a microscopic hole (5), which bottles (1) are then sealed in a closed vessel (6) of flexible and non-corrodible material, the cover of which becomes loose when too high a pressure is formed inside the vessel (6) and which cover (7) can be sealed again by pressing it closely when the pressure has been released from the vessel.
